(ll.22-24)Almost none of the analogies that have been used so far can fully describe what teaching is all about, (or: Nearly all the analogies that have been used so far can only present a partial picture, rather than a complete one, of what teaching is really about.) In this sense, none of them serves as an apt analogy for teaching.2.Rather than emphasizing the mutuality of the endeavor, each of these common analogies turnson a separation between the professional and his clients. (ll. 30-32)Each of these popular analogies sees the teacher and his students not as an organic unit tied together in a joint effort, but as being isolated from each other.3.The teacher as actor also plays to a passive audience, but he measures success by largenumbers. (l. 48)The teacher, seen in the role of the actor, would be simply lecturing to an audience, who donot participate, and he would evaluate his performance not by their involvement in class activities, but by the size of the class.4.The mountaineer accepts his leadership role, yet recognizes that the success of the journey(measured by the scaling of the heights) depends upon close cooperation and active participation by each member of the group. (ll.76-78)The mountaineer knows his own function as a leader and is well aware, too, that whether they can climb to the top is decided by how well each member can cooperate with the others and how far each member is ready to involve himself in the endeavor.5.Essential skills must be mastered if the trip is to be successful; lacking them, disaster looms asan ominous possibility. (ll. 79-80)For a good journey, basic skills form an indispensable part, without which one is likely to encounter misfortune.V.Write a short essay, trying to make your reader accept that practice is the most effective way to improve your spoken English.
